Exercise - Uses and Separations:

Proposed: Type II-B Construction, No Sprinkler

First step: is to calculate the sizes of each separate use.

Second step: is to determine which use(s) qualifies as an “Accessory” Use (Section 508.2)?

Third step: is to determine which uses are considered a mixed use.

Fourth step: is to determine which type of separation is required between the mixed use(s). The choices are:
